FIELD TECH II - III CONVENTIONAL COMPLETE
QUESTIONS AND CORRECT DETAILED ANSWERS
(VERIFIED ANSWERS)
QUESTION: What is one reason why broadband cable operators
install fiber-optic cable in stages instead of changing the
infrastructure all at once?
Ans: Changing the infrastructure all at once would cause too many service
disruptions.
QUESTION: What is the difference between the fiber-to-the-node
(FTTN) and fiber-to-the-curb (FTTC) topologies?
Ans: An FTTC is allowed a smaller number of RF amplifiers between the optical
fiber and the customer premises.
QUESTION: Which type of star topology used in a passive optical
network (PON) places the PON splitters into fiber access terminal
(FAT) located deep in the network and closer to the customer
premises than the centralized split?
Ans: Distributed star.

QUESTION: Which element of a passive optical network (PON) uses a
Bragg grating filter?
Ans: Optical line terminal (OLT).
QUESTION: Which element of a passive optical network (PON) uses
patch panels?
Ans: Optical distribution network (ODN).
QUESTION: What is it about radio frequency over glass (RFoG) that
made broadband cable operators envision using it to make a
seamless transition from the legacy hybrid fiber/coax (HFC)
architecture over to a gigabit-capable passive optical network
(GPON) or Ethernet passive optical network (EPON)?
Ans: RFoG can operate in parallel with GPON or EPON, which eliminates the need
for any downtime during the transition.

Ans: In the forward path, optical splitters are used as passive branching devices
that divide an optical signal across multiple output fibers.
QUESTION: Which of the following describes a fiber pigtail?
Ans: Fiber-optic cable with pre-connectorized ends.
QUESTION: Heat shrink tubing is installed over the fusion-splice to
strengthen and protect it. When should the heat shrink be installed
on the fiber?
Ans: Before stripping the plastic coating from the fiber.
QUESTION: Which of these components is used in a passive optical
network (PON)?
Ans: Optical splitters
QUESTION: Which of the following are statements of true axioms?
Ans: When A = C and B = C, then A = B because both are equal to C, which
supports the axiom: Quantities equal to the same quantity are equal to each
other.

QUESTION: Simplify and solve the equation: If E = IR then I = ?
Ans: E/R
QUESTION: The square of 7 =
Ans: 49
QUESTION: The square root of 81 =
Ans: 9
QUESTION: 0.00004 = ______ x 10 to the power of ______.
Ans: 4, -5
QUESTION: (75 x 10 to the power of 3) + (25 x 10 to the power of 4)
=
Ans: 32.5 x 10 to the power of 4
QUESTION: 10 to the power of -3 has a metric prefix of ______.
Ans: Milli
